DEVICE TESTS TOOL
Gyroscope / Accelerometer Tester
Test motion sensors with live tilt, acceleration, and rotation readouts.
Works on phones and tablets with motion sensors. On iOS, tap "Enable sensors" first to grant permission — Android and most other browsers start automatically.
About this tool
Check that your phone or tablet's motion sensors work — live orientation angles (compass heading and tilt), acceleration, and rotation rate, plus a simple bubble-level visualization that moves as you tilt the device. All readings come straight from the browser's motion APIs; nothing is recorded or sent anywhere.
Frequently asked questions
- Why do I need to tap "Enable sensors" on iPhone/iPad but not other devices?
- iOS 13 and later require an explicit user gesture (a tap) before a webpage can request motion/orientation permission, for privacy reasons — Android and desktop browsers generally don't have this extra permission step.
- Why does "Acceleration" show nothing, while orientation works fine?
- Some devices only expose acceleration including gravity rather than gravity-isolated acceleration — if the plain acceleration reading stays empty, that's a hardware/driver limitation on that specific device, not a bug here.
- Nothing updates at all — what's wrong?
- You're most likely on a desktop or laptop without motion sensors, where these events simply never fire — this test is meant for phones and tablets. Also double check the page is loaded over HTTPS, which most browsers require for motion sensor access.
